Bjorn,
That is certainly a sought after part and it would be great if a metal repro became available. Just recently I was able to obtain a good used baffle and have been restoring it. I will soon replace a fiberglass repro that's on my '68.
I wanted to point out that the parts catalog shows different part numbers for the '67-'68 (9789451) and the '69 (9796251) for the "valance/front panel to sheetmetal baffle". I don't know what differences there are between them but that may affect your project.
